JEWELRY CLASP.

Application filed April 26, 1826. Serial No. 104,551.

above, which will be extremely strong and sturdy and shall have a minimum of parts so that the possibility of breakage is avoided.

lVith these objects and such other objects as may hereinafter appear, in view, I have devised the particular arrangement of parts hereinafter set forth and more particularly pointed out in the claims appended hereto.

Reference is to be had to the accompanying drawing, forming a part hereof in which- Figure l is a rear elevation of my improved clasp.

Figure 2 is a sectional view of the two locking members of the clasp shown sep arated from one another.

Figure 8 is a vertical sectional View of the clasp with the parts united and in locked position.

Figure 4: is a transverse sectional view of the two locking members of the clasp in separated condition.

Figure is a sectional view on the line of Figure 1, looking in the direction of the arrows,

Figure 6 is a sectional view on the line 66 of Figure 1; and

Figure 7 is a sectional view on the line 77 of Figure 2 looking in the direction of the arrows.

Throughout the various views of the drawings similar reference characters designate similar parts,

In the preferred embodiment of my invention as disclosed in the accompanying drawing, the article is composed of two main parts, the same consisting of a plate 1 and another plate 2. These two plates are adapted to be interlocked or engaged as will be hereinafter set forth and they are usually secured to the ends of the bracelet 3 and 4, which is diagrammatically illustrated.

The plates 1 and 2- are shown as being provided with settings 5 for the reception of gems or the like. Assuming therefore, that the plates 1 and 2 are secured to the ends of the bracelet parts 3 and l, said plates overlie one another when in their engaged positions and the plate 1 is provided on its back face with a projecting tubular locking guide 6 which passes through an aperture 7 provided in. the plate 2. Said plate 2 is provided with similar guides 8 and 9 and said guides are located on opposite sides of the aperture 7 so that when the locking guide 6 is projected through said aperture, it will. be located in alignment with the two locking guides 8 and 9 and a suitable locking pin 10 may he slid through the three aligned guides (3, 8 and 9 to firmly secure the plates 1 and 2 together in locked position.

As will be seen from Figures 4, 6 and 7, the locking guide member 6 on the plate 1 stands out a considerable distance from the back face of the plate 1 and is provided with narrowed portions or grooves 11. Thus, when the locking guide 6 is projected through the opening 7, these grooves 11 are resiliently engaged by wire springs 12 which are secured near their ends as at 13 to the back face of the plate 2. These springs 12 have their central parts slightly distorted inwardly or toward one another so that these parts readily snap into engagement with the grooves 11. and resiliently grip the same and firmly unite the plates 1 and 2.

In addition to this form of fastening, another measure of protection is afforded by means of the locking pin 10 which is then pushed downwardly through the guides 6, 8 and 9 and assumes the locked position disclosed in Figures 1 and 3.

The pin 10 is composed of a head 14 which may be gripped by the hand to raise and lower the same and it also has a pair of spring legs which are expanded outwardly from one another. The lower ends of the spring legs 15 are united as at 16 and to prevent the pin from being disengaged from the device or become lost, a cross-piece 17 is provided in the upper end of the guide 8, said cross-piece 17 extending bet-ween the legs 15 of the locking pin as is clearly shown in Figures 2, 3 and 7.

From the foregoing, it will be apparent that an extremely secure fastening device is provided. The plates 1 and 2 snap into engagement by the resilient gripping of the springs 12 with the grooved parts 11 of the plate 1. The engagement thus afforded between the parts is a secure One but since on the first plate for engaging with parts the clasp is adapted for use upon valuable articles of jewelry, every safeguard must be availed of and a further positive locking arrangement is made'use of through the medium of the pin 10 which is thrust downward through the three aligned guides 6, S and 9, said pin 10 resiliently maintaining itself in the position shown in Figures 3 and 6 by firmly gripping the sides of the aligned guides with its spring legs 15.

7 To open the clasp, the pin 10 is drawn out as shown in Figure 2 by gripping the head 14; and the plates 1 and 2 may then be readily separated by raising the plate 1 by means of the finger-hold 18 provided on said plate.

' Having described one embodiment of my invention, it is obvious that the same is not to be restricted thereto,but is broad enough to cover all structures coming within the scope of the annexed claims.

What I claimis: 1. An article of the class described comprising a plate having an opening, spring 2. An article of the class described cornprising a first plate and asecond plate, a pair of tubular guide members on the back of said first plate, an opening in said first plate located between said guide members, a guide member on the back face of the second plate adapted to extend through-the opening in" the first plate and align with the guide members on said first plate, spring means of the guide member on the second plate and gripping the same and holding it in alignment with the guide members on the first plate and a locking pin held in one of the guide members and adapted to befrom the back of said plate on opposite sides of said opening, a similar tubular guide projecting from the back face of the second plate and adapted to project through the opening in the first plate and lie in alignment with the other guides when so located, grooves located in the second plate a pair oi spring wires disposed along the edges of said opening and adapted to resiliently engage with the grooves, and a locking pin adapted to pass through the three guides when the same are aligned with one another.

4 An article of the class described comprising a pair of engaging plates, guide members on said plates adapted to align with one another when the plates are engaged, a locking member adapted to be moved through the guide members to unite the plates, said locking member having a pair of spring legs for resiliently engaging the walls of the guides through which it passes, said legs being united at their ends and a strip extending across one of the guides between the spring legs onthe locking'member and ,actingras a staying piece forsaid locking member.
